Hi please someone help! Maybe this is more legal...?
Anyway we have an offer accepted on our house our solicitor asked us for a number of docs and we supplied everything we have...they then came back and said they need- Planning Permissions/Building Regulation Approvals/ Completion Certificate
We bought the house in 2013 brand new build from a well known builder. And i cannot find this information! Everything I ever received has been kept safe in a file and i dont recall ever seeing these 
What do I do next? Is the house sale doomed! Any experiences or advice much appreciated
